We evaluated an inspection system in our plant about 8 months ago which
stored frames of video onto a 3 1/2" hard drive. The idea was to store an
image of a perfect circuit board in the system, then electronically compare
it to a live image of the same board type.

It's difficult to get any hard technical details from a salesman but as I 
understand it, one frame takes up one track on the media. One field is on 
side one and one field is on side two. As the disk rotates, it switches from
one side to the other to construct the full frame.

They also had a sharp security system for a guard gate where a person would
'swipe' his badge through a reader and the system would display his picture
on a monitor in the guard station. Picture no match - person no enter.

If you need it, I can dig out the file and give you their company details.
